cannot resolve symbol javafx.application in IntelliJ Idea IDE


I tried to create a JavaFX application in IntelliJ Idea IDE but I got compile error that said:

java: package javafx.application does not exist.

I have changed the Project SDK and the Project Language Level to Java 8, reloaded the project but it didn't help. Then I checked if JavaFX plugin was enabled in the settings.

The search on Google and StackOverflow didn't give me more ideas of what is wrong. Thank for any help in advance.

P.S. I am using IntelliJ Idea 14.0 with java8.1.0_25 on archlinux OS.

As indicated here, JavaFX is no longer included in openjdk.

So check, if you have <Java SDK root>/jre/lib/ext/jfxrt.jar on your classpath under Project Structure -> SDKs -> 1.x -> Classpath? If not, that could be why. Try adding it and see if that fixes your issue, e.g. on Ubuntu, install then openjfx package with sudo apt-get install openjfx.

This should be your perfect solution. Try and enjoy. If some command does not work properly that means if you get any error, try to solve it yourself. I have given you the main thing you need. If your application is in a different location, or your system architecture is different, solve it yourself. It's very easy to do it. Just follow my given solution.

Step 0:

sudo apt-get install openjdk-8-jre

Step: 1

sudo apt-get install openjfx

Step 2:

sudo cp /usr/share/java/openjfx/jre/lib/ext/* /usr/lib/jvm/java-1.8.0-openjdk-amd64/lib

Step 3:

sudo cp /usr/share/java/openjfx/lib/* /usr/lib/jvm/java-1.8.0-openjdk-amd64/lib

Step 4:

sudo chmod 777 -R /usr/lib/jvm/java-1.8.0-openjdk-amd64

now open a new project or rebuild your project. Good luck.
